((51. -40) 1 Myinvention relates to an improved safetytype: razor and a dispenser forinserting. blades; in. said razor. My invention is particularly" adaptedto be usedwith double-edged blades.

In my invention,.I split the transverse walls. of: the razor bladechamber longitudinally to. divide;

it into two. portions. These chamber portions are.

normally held together by spring. action. so that they frictionallyengage the. side cutting. edges. of a blade positioned in the chamberand thereby prevent lateral movement of said; blade and inhibitlongitudinal movement thereof I provide the dispenser with a-boss ononev end: thereof; This. boss may be releasably, but securely'.interfitted with one end of the-razor and serves as wedge means tospread the blade chamber portions. As a result, the frictionalengagement of the side edgesof the" blade is relaxed, and a new bladedispensed from'the dispenser may readily be inserted into the chamberthereby ejecting the old blade.

I thus provide an economically constructed and easily operatedrazor-dispenser unit. The razor is preferably used with double-edgedblades, and new blades may be readily inserted therein by means of thedispenser.

Other objects and advantages ofmy invention will become apparent in thefollowing description and in the annexed drawings, in whicha preferredembodiment-is shown.

In the drawings: I

Fig. 2 is a view similar to Fig. 1, showing the dispenser attached tothe razor. The broken lines show the positions or the slider handle andthe old blade in the razor when said slider handle is moved part waytoward ejecting position;

Fig. 3 is a section on the line 3-3 of Fig.2;

Fig. 4 isa view similar to Fig. 3 showing the" positions of the partswhilethe slider is being moved to eject the used razor blade; I v

Fig. 5 is a views'imnar to FigsQ3jand'4, showing the slider returned toits initial positionafter the used blade hasbeen ejected from the razorand a new blade'i'nserted;

Fig. 6 is a section, on the line .6'--6; ofFigs 5;

Fig. 7 isa rear elevation 'of the-dispenser; and

Fig. 8 is a frontelevation of the razor. The front end of the dispenseris adapted'to engage therear end of the-razor.

olely for the. convenience'in descrlptionrl define the end of 'razoriRshown: in Fig. 8 as the Irene-end thereof; and rd'efine the end of dis-2. penser D shown in Fig. 7 as the rear end thereof. Referring to thedrawings in detail, it is seen that I provide a razor R whose bladechamber is divided into chamber portions M and-N by means of slits l3which respectively extend the entire length of respective uppertransverse wall [5, l5 and; lower transverse wall IE, l6; 19 of thisblade chamber M, N are respectively connected by leg members ll) tohandle ll, and I provide suitable spring means I2 to urge these legs I0toward each other. As a result, walls l9 normally frictionally engagethe side edges of. a bladeB positioned in chamber M, N and preventlateral movement and hamper longitudinal movef ment of said blade B.

I also provide a dispenser D which has a boss 21 formed on the rear endthereof. I form the front portion. of razor R, as well as this boss 21,

in such a manner that they may be releasably,

butsecurely, interfitted together; Boss, 21 serves to wedge walls l9.apart. and thereby sufiiciently relaxthe frictional engagement of theside edges of blade B. to facilitate longitudinal movement thereof.

Dispenser D. is adapted to. dispense a blade 3' longitudinally. throughslot 23 in the rear thereof.

When razor R and dispenser D are interfitted,

this blade: B is. so positioned that it enters blade chamber M, N as it.is dispensed. As the dispensing action continues, and because walls l9are maintained in spread.v position, blade B replaces blade B in chamberM, N and blade B isejected.

Blade holding means of razorl- I provide razor R with a blade chamber M.N

which is approximately. the size of the preferably double-edged blade Bwhich I provide. This blade B may be. inserted and ejected longitudinal-1y from. this chamber M, N but is normally sub-- stantially free. fromother movement. Blade Bis optionally tapered. at its ends to facilitateits insertion in chamber M, N.

Chamber. M; N comprises respective substantially' parallel upper. andlower transverse walls I5, l5 and l6, I,6,. which are separated by a distanceslightly greater than the thickness of blade B, whereby theyallowonly slight vertical play Chamber M, N isopen at each end and has Sidewallsi 3 side walls M which extend below wall l6, l6 and in front ofwalls l5, l5 and l6, l6. Chamber portions M and N respectively comprisea respective wall M, together with the members l5 and I6 attachedthereto.

A leg member ID is attached to each side wall l4 and extends downwardly.These legs l0 converge toward each other and are secured inside hollowhandle ll. Legs II) are slightly resilient, and I provide spring meansl2 which normally urge said legs [0 toward each other. Spring [2 is madeof spring steel and is preferably V- shaped, its legs being respectivelymounted along the inside surfaces of respective legs 10 and its basebeing located within handle l I. Optionally, any other suitableconstruction may be utilized for spring I2.

I provide longitudinal cut-outs a which respectively extend from pointsadjacent the front end of razor R to points adjacent the rear endthereof and are respectively located in the outer portions of wallmembers 15 and upper portions of walls [9. These cut-outs l5a exposemost of the side cutting edges of a blade B disposed in chamber M, N.The end portions of walls I9, which have not been cut away at 15a,normally abut the ends of the side cutting edges of blade B and grip itsufficiently firmly to make it relatively difiicult to causelongitudinal movement thereof. Blade B is frictionally engaged by sidewalls [9.

Optionally, longitudinal slots may be formed in wall members 16 tofacilitate shaving and to aid in cleaning razor R.

Dispensing means of dispenser Dispenser D is substantially rectangularin shape and is adapted to hold a blade B in abutment with its top walland a plurality of blades 3' beneath blade B. These blades B and B abuteach other and are alined in the direction of the axis of dispenser D.They are held adjacent the rear end wall of dispenser D by means of stoppins 9, which depend from the top wall of said dispenser D. These pins 9are spaced from the front end wall of dispenser D and check the forwardmovement of blades B, B. Blades B, B are held vertically in position bymeans of strip spring 2|, which is alined in the direction of the axisof dispenser D and has a base portion held in a longitudinal trough 22in the base of said dispenser D. Spring 2| is curved so that it hasupper portions 2Ia near its ends which abut the bottom blade B" and urgeit upwardly.

I provide a slider which is positioned adjacent the undersurface of thetop wall of dispenser D. I also provide a groove 24, which extendsalmost the entire length of said top wall of dispenser D, and a fingerpiece 26 is located outside said dispenser D, abutting the top thereof.This finger piece 26 is connected to slider 25 by securing meansextending vertically through groove 24'. Slider 25 extends somewhat infront of finger piece 26 and the member connecting slider 25 to saidfinger piece 26, so that when finger piece 26 is moved to the rear limitof groove 24, the leading edge of slider 25 extends through slot 23 tothe front end of dispenser D.

I also provide a horizontal slot 23 at the top of the rear wall ofdispenser D. Slider 25 is no thicker than blade B and may be moved fromthe position of Fig. 3, in the direction of the arrow of Fig. 4, todispense blade B through said slot 23. Slider 25 is free to pass betweenpins 9.

Interfitting of dispenser and razor As stated above, I provide a boss 21on the rear end wall of dispenser D to serve as wedge means. This boss21 is slightly narrower than said rear end wall of dispenser D, and theface of boss 21 is slightly rounded. Vertical grooves 29 are formed oneach side of boss 21, and. a horizontal groove 28 is formed extendingacross the face of said boss 21.

I provide transverse vertical flanges M which respectively projectinwardly from the front edges of respective razor walls l9 andpreferably extend the entire height of these walls [9. These flanges Mare respectively notched or grooved at [8 to permit passage of blade Bfrom slot 23 of dispenser D into blade chamber M, N of razor R.

As is clearly shown in Figs. 1 and 2, when the axis of dispenser D isalined with the axis of razor R boss 21 is inserted between flanges l4,chamber portions M and N are spread apart. This is because boss 21 iswider than the distance between flanges Hi. In the inserted position ofv Fig. 2, boss 21 separates the front end portions of chambers M and N,and therefore of walls l9, considerably; but the separation graduallydecreases rearwardly, and there is little or no separation of the rearend portions of walls [9. Slit l3 assumes a V-shape.

The result of the insertion of boss 21 between flanges I4 is that thefront end portions of the side edges of blade B are no longerfrictionally engaged by walls l9. In other words, the side edges ofblade B are frictionally engaged by walls 19 only at the rear endportion of said side edges. It is therefore easy to insert blade B andsimultaneously eject blade B. However, when blade B is inserted, it isprevented from falling out until dispenser D is removed from engagementwith razor R, because the front portions of the side edges of blade Bare held by walls 19.

When boss 21 is inserted between flanges l4, these flanges l4respectively lock releasably into place in respective grooves 29. Theassembly is properly positioned by means of pins 20, which respectivelyprotrude inwardly from respective walls l9 and are positioned in groove28 of boss 21.

I also provide horizontal guide flanges l1 which respectively extendinwardly from the top edges of respective walls IS in front of the frontedges of respective wall members [5. When dispenser D and razor R areassembled, these flanges l1 are disposed above the top wall of dispenserD in abutting relationship thereto. The interfitting of pins 20 ingroove 28 and of flanges 11 on the top wall of dispenser D control thevertical position of dispenser D in relation to razor R, so that whenblade B is dispensed through slot 23, it will move properly into chamberM, N.

I preferably dimension the parts in such a manner that when dispenser Dand razor R are interfltted, slot 23 abuts or very nearly abuts the openend of chamber M, N.

Operation of device The above-described construction leads to a simpleoperation of the device to replace a used blade B by a new blade B.

I grasp razor R in one hand and dispenser D in the other hand and movethe rear end of dispenser D adjacent the front end of razor R, as shownin Fig. 1. I then place the top wall of dispenser D in abutmentwith theunder surfaces of flanges l1 and slide dispenser D until flanges l4 snapinto grooves 29. This position is shown in Figs. 2 and 3.

In this position, as is shown in Fig. 3, finger piece 26 is located atthe rear of groove 24, and

slider 25 is behind blade B. I then slide slider 25 forwardly by meansof finger piece 26. Fig. 4 shows an intermediate position of slider 25and shows blade B entering chamber M, N and pushing blade B out of saidchamber M, N. Slider 25 is moved to its extreme forward position,whereby blade B is completely inserted in chamber M, N, and blade B iscompletely ejected therefrom.

I then return slider 25 to its original position, as shown in Fig. 5,and remove dispenser D from engagement with razor R. As is shown in Fig.5, a new blade B" now abuts the top wall of dispenser Band is inposition to be dispensed therefrom.

I have shown a preferred embodiment of my invention and have indicatedcertain changes which may be made therein. Various other modifications,additions and omissions may be made in my invention without departingfrom the scope and spirit thereof.

I have shown a razor blade chamber split into portions M and N, asdescribed. Various spring means may be used to hold these chamberportions M and N together. While I have shown one construction of razorR and dispenser D whereby the latter may be used to wedge chamberportions M and N apart, this construction may be modified to provideother suitable wedge means. Guide means l1 and 20 may be replaced byother suitable guide means, and locking means [4, 29 may be replaced byother suitable locking means.

The above changes, modifications and omissions are not all-inclusive.

I claim:

In combination, a safety-type razor for doubleedged blades and a bladedispenser, said razor comprising a blade chamber which is open at eachend whereby blades may be inserted and ejected longitudinally therefrom,the upper and lower walls of said blade chamber respectively havinglongitudinal slits therein extending the entire length thereof wherebysaid chamber is divided into two portions, a handle connecting saidchamber portions, spring means tensioning said chamber portions towardeach other whereby the side cutting edges of a double-edged bladepositioned within said'blade chamber are frictionally engaged by theside walls of said blade chamber, and dispenser receiving means, saiddispenser receiving means comprising respective extensions of the sidewalls of said blade chamber beyond the transverse walls thereof, thefront ends of said wall extensions being turned inwardly to formopposing guide flanges, and opposing pins projecting inwardly from saidwall extensions, said'dispenser having a leading end portion which isless wide than the dispenser main portion, said dispenser having atransverse slot in the leading end wall thereof and means for ejecting ablade longitudinally through said slot, said leading end wall having atransverse pin groove therein, said leading end portion havingtransverse locking grooves in the respective side walls thereof, saiddispenser and said razor being releasably engageable whereby saidlocking flanges are respectively positioned in said locking grooves,said pins are positioned in said pin groove, the undersurfaces of saidguide flanges abut the top wall of said dispenser, and said dispenserslot abuts an end opening of said blade chamber, said dispenser leadingend portion spreading said chamber portions when said dispenser and saidrazor are releasably engaged.
